Can't bind to [(ngModel)] since it is not provided by any applicable directives
时间: 2024-03-06 10:47:23 浏览: 18
This error message is related to Angular. It usually happens when you try to use the ngModel directive without importing the FormsModule in your Angular module.
To fix this error, you need to import the FormsModule in your module where you want to use [(ngModel)] directive. You can do this by adding the following line in your module:
```
import { FormsModule } from '@angular/forms';
@NgModule({
imports: [
FormsModule
]
})
```
This will import the FormsModule and make the [(ngModel)] directive available in your component.

Can't bind to 'ngModel' since it isn't a known property of 'input'.
回答: 当出现"Can't bind to 'ngModel' since it isn't a known property of 'input'"错误时,这是因为没有在当前组件所属的模块中引用FormsModule。要解决这个问题,你需要在当前组件所属的模块中添加FormsModule的引用。具体做法是在module.ts文件中添加以下代码:import { FormsModule } from '@angular/forms';然后在imports数组中加入FormsModule。这样就可以解决"Can't bind to 'ngModel' since it isn't a known property of 'input'"错误了。\[1\]\[2\]\[3\]

Can't bind to 'formGroup' since it isn't a known property of 'form'
This error message usually occurs when the Angular form module is not imported correctly in your component or module file. To fix the error, you can follow these steps:
1. Make sure that you have imported the FormsModule or ReactiveFormsModule in your module file. For example, in your app.module.ts:
```
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms'; // Import the form modules
import { AppComponent } from './app.component';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule, // Add the FormsModule here
ReactiveFormsModule // Add the ReactiveFormsModule here
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
```
2. If you have already imported the form module, check if you have spelled the formGroup correctly in your component. Make sure that it is written as 'formGroup' with a capital 'G' and not 'formgroup' or 'FormGroup'.
3. Ensure that you have added the form tags correctly in your component HTML file. For example, if you are using a reactive form, your HTML code should look like this:
```
<form [formGroup]="myForm">
<!-- form controls -->
</form>
```
By following these steps, you should be able to fix the "Can't bind to 'formGroup' since it isn't a known property of 'form'" error.
